在这篇文章中的实用程序的亚磷酰胺配体在对映选择性的AuI催化的发展中探索了高度非对映和对映选择性的AuI催化的联烯环加成。本文报道了Au Ⅰ催化合成3,4-二取代吡咯烷和γ-内酰胺的方法。该反应通过对映选择性AuI催化的联烯环化反应进行,以形成被外源亲核试剂捕获的碳阳离子中间体,从而导致三个连续立体中心的高度非对映选择性构建。计算研究(DFT)也进行了一些深入了解这些环加成的潜在机制。这种新方法的实用性通过(-)-异氰米曲碱的正式合成得到了证明。
In this article the utility of phosphoramidite ligands in enantioselective AuI catalysis was explored in the development of highly diastereo- and enantioselective AuI-catalyzed cycloadditions of allenenes. A AuI-catalyzed synthesis of 3,4-disubstituted pyrrolidines and γ-lactams is described. This reaction proceeds through the enantioselective AuI-catalyzed cyclization of allenenes to form a carbocationic intermediate that is trapped by an exogenous nucleophile, resulting in the highly diastereoselective construction of three contiguous stereogenic centers. A computational study (DFT) was also performed to gain some insight into the underlying mechanisms of these cycloadditions. The utility of this new methodology was demonstrated through the formal synthesis of (–)-isocynometrine.
